Hydration and Acid Reflux: What You Need to Know
Staying hydrated is essential for our health, but how we drink water might negatively affect digestion over time and make acid reflux symptoms worse, according to a leading dietician.
Although opting for water instead of sugary drinks like Coca-Cola is certainly a healthier choice, experts caution that it’s not a cure-all for reflux symptoms.
Molly Pelletier, a dietician and specialist in acid reflux, recently took to Instagram to explain how consuming water can, in some cases, trigger issues like heartburn and bloating.
In her post, she reflected on how her life might have been different had she understood earlier that her water-drinking habits were contributing to her discomfort.
Acid reflux happens when stomach acid flows back into the esophagus, resulting in that cringe-inducing burning sensation known as heartburn.
Pelletier noted that timing and method are just as important as the type of liquid consumed. She mentioned that chugging water during meals or drinking cold water on an empty stomach could unintentionally provoke symptoms like throat clearing and regurgitation.
The lower esophageal sphincter typically keeps stomach acid in check, but if it weakens or malfunction at the wrong moment, irritation can occur.
Common trigger factors for acid reflux include stress, rapid eating, and certain foods like alcohol and chocolate. However, Pelletier warns that drinking excessive amounts of water quickly—especially alongside meals—might also be exacerbating symptoms.
“Sip slowly—especially during meals. Think gentle hydration, not flooding your stomach,” she advised her followers.
She also suggested hydrating between meals rather than right before or after eating. For most people, sipping water with meals isn’t inherently harmful, but it can increase the stomach’s volume, putting extra pressure on the valve that keeps stomach acid where it belongs.
Kitty Broihier, another registered dietician, emphasized that drinking water with large meals could lead to a feeling of bloating. Research supports this, indicating that stomach distension can increase the amount of acid reaching the esophageal sphincter, forcing it back up and leading to discomfort.
Broihier warned, “As beneficial as water is, consuming a lot at once can worsen distension.” She added that it’s better to hydrate throughout the day rather than trying to catch up at night.
Pelletier also recommended room temperature water, as it’s absorbed more efficiently and can be easier on the stomach.
For those still experiencing reflux despite following general advice, hydration habits might be worth reconsidering, she noted. Medical professionals can also provide personalized guidance or medications to address the issue.
If left untreated, acid reflux could eventually lead to a condition called Barrett’s esophagus, which can increase the likelihood of esophageal cancer.
This year, health experts warned that many may be reliant on proton pump inhibitors (PPIs), which alleviate heartburn by reducing stomach acid. However, stopping these medications often leads to a rebound effect, worsening reflux symptoms.
Cancer Research UK estimates that a small percentage of Barrett’s esophagus cases will progress to cancer, giving those affected an 11-fold increased risk compared to those without the condition.
Overall, it’s estimated that a significant number of esophageal cancer cases could be preventable, with projections suggesting a dramatic increase in cases by 2040.
